I, About Plastic single wall corrugated pipe mould block
The single-wall corrugated pipe module is the core component of a corrugated pipe forming machine. Its function is to continuously "press" out the corrugated shape on the pipe wall while the pipe blank is still hot through closed extrusion.
Core Function: The module is a key component that directly determines the corrugated pipe waveform (e.g., U-shape, V-shape), corrugation pitch, corrugation depth, and final pipe diameter. In high-speed production such as "dual-outlet" systems, a single-mold, dual-diameter module can also reduce costs.
Structure and Motion: The equipment typically has two opposing module chains, each chain consisting of numerous individual modules connected end-to-end to form a closed loop. During production, the modules on both sides precisely align and move forward within the "forming tunnel," completing the extrusion forming of the pipe blank.
Material and Cooling: To ensure high precision and durability, the modules are typically made of hard alloy steel. Simultaneously, the module is designed with internal cooling water channels, using circulating cooling water for rapid cooling to ensure high-speed pipe shaping.
II, Customized Plastic single wall corrugated pipe mould block
1,Thickened Module: Increasing the module width from the common 157mm to 314mm improves operational stability, reduces malfunctions, and thus enhances product quality.
2,Adjustable Waveform: An innovative design allows the module's protrusions to extend and retract within a certain range. This enables the same module to produce pipes with different waveforms, significantly reducing mold replacement and inventory costs.
3,Rectangular Pipe Module: For square single-wall corrugated pipes, the module features square crests and reinforcing grooves inside, resulting in better forming effects and enhanced pipe pressure resistance.
4. Engraving on the inner wall of the module to add a logo: The style, size, and position of the customer's logo can be engraved on the inner wall of the module, creating a brand identifier or specific mark on the corrugated pipe surface.
5. Double-cavity or triple-cavity modules: On a high-speed production line for single-wall corrugated pipes, one module can simultaneously process double-cavity or even triple-cavity corrugated pipes.
This method offers several significant advantages:
Saving mold investment costs: A single investment in a multi-cavity module is equivalent to the function of multiple traditional single-cavity modules.
Saving mold changeover time: When changing product specifications, switching can be done in a single operation, reducing downtime.
Increasing production efficiency: The output of the same machine can be doubled within the same time frame.
6. Vacuum suction irregular-shaped modules: This requirement also has technical solutions, mainly addressing the forming problem of special-shaped pipes.
Irregular-shaped forming: A patent for a high-speed single-wall corrugated pipe forming machine explicitly mentions that the equipment "can process various irregular-shaped pipes." This provides the equipment basis for customizing non-circular corrugated pipe modules.
Vacuum suction design: There are already specific patented designs combining "vacuum suction" and "irregular shapes". For example, a socket module for SFIP square single-wall reinforced corrugated pipes features vacuum channels and venting grooves on the outer side of the corrugations. This structure, aided by vacuum suction, ensures precise corrugation shaping and improves the pipe's pressure resistance.
